Abstract:
A GOA driving circuit is disclosed. The GOA driving circuit includes download units. Each of the download units includes a download transistor and a voltage stabilization capacitor. One plate of the voltage stabilization capacitor is connected to a source of the download transistor, and the other plate of the voltage stabilization capacitor is connected to a common electrode. The common electrode transmits a direct current voltage signal. The voltage stabilization capacitor generates a coupling voltage so as to maintain stabilization of the download signal. A reliability of signals of key nodes in the driving circuit can be improved, and a display stability of a liquid crystal panel can be improved accordingly.
